PrismaCircuit Monitors Electrical Faults and Physical Threats for Better Grid Resiliency.

How it works

Distributed Monitoring for Full Grid Coverage

As our aging power grid struggles to meet increasing demand and the complexity of integrating renewable energy sources, environmental challenges like extreme weather amplify the situation, leading to more frequent and severe power outages.

PrismaCircuit™, a part of the PrismaPower™ suite of grid monitoring solutions, is a Grid Enhancing Technology that offers a modern and quick way to monitor and increase a grid’s resiliency at a large scale. It alerts in real-time for electrical events and faults, physical tampering with the towers, climbs, and vegetation hits all along the grid’s length for thousands of kilometers or miles without installing additional sensors on wires or towers.

PrismaCircuit helps ensure the grid’s security and reliability while minimizing operational and maintenance costs by pinpointing in real-time and directly locating fast-occurring events such as short circuits and slow-moving processes like partial discharge buildup.


We’ve put together everything you should know about PrismaCircuit in a nifty two-page brochure.

Solution Architecture

For the last 20 years, transmission system operators have deployed fiber optic cables as part of their transmission grid. PrismaCircuit turns the existing Optical Ground Wire (OPGW) into a set of highly sensitive distributed sensors extending for hundreds and thousands of kilometers or miles. The solution connects to one single dark fiber at a substation, sensing the grid. PrismaCircuit’s machine learning algorithms take the detailed data collected on the grid to detect and classify events, pinpointing them down to tower locations in real-time. 

All the information and alerts are concentrated into one command and control center so PrismaCircuit can continue scaling with the grid. PrismaCircuit is your way to take off some of the burdens of responsibility.
